wasted time!!

I was a my regular day job yesterday and I received a call from a potential customer wanted to know how much I would charge to mow her lawn. So I made my way to her house, come to find out she wasn't home and her either husband or boyfriend was home had no clue that I was stopping by. As I approached the house I looking at her lawn. There are leaves all over the lawn the grass needed to be cut last week and best of all. I notice that there are a tone of pine cones all over the side of the house. So I quoted her $150.00 for a first cut/clean up and she wanted some mulch put down but didn't have a clue what she wanted so I didn't quote her on that . I haven't heard back from her yet and I don't expect to here from her either. You got love people that waste your time. I get a little upset over stupidity
